Variable Speed Refrigeration Dryers

CD-VS Series

A Next Generation Energy Saving Variable Speed Refrigeration Dryer

Cycling & Non-Cycling

Refrigeration Dryers

First-class air treatment efficiency

The low environmental impact R513A refrigerant gas combined with a variable speed operation is the height of technological evolution and maximises respect for the environment. By using inverters, it is possible to modulate the electrical power input by the scroll compressor and fans according to the thermal load required by the user.

ADVANTAGES:

  • Greater environmental friendliness
  • Reduced running cost
  • Optimised consumption and performance under all load conditions

Many testing hours in our R&D laboratories have confirmed the reliability, robustness and performance of the new CD-VS range, made of high quality materials, mechanical and electronic components from leading international brands in the industrial refrigeration sector.

CompAir Industrial Variable Speed Dryer

Eco-friendly R513A refrigerant

The CD-VS refrigeration dryer series uses the environmentally friendly R513A refrigerant gas with low GWP, which is non-toxic and non-flammable, and makes it possible to install CD-VS units indoors. The CD-VS dryers wide operating limits meet the most diverse industrial demands.

Low Global Warming Potential

Variable speed

Variable speed dryers, using inverter technology for compressor and fans, can adapt their energy consumption according to the thermal load applied, and adjust the refrigerant flow rate to the ALU-DRY heat exchanger. With the new DMC55 controller and electronic EHGBV hot gas bypass valve, the user can choose between Cycling or No-Cycling operation for extremely low heat loads.

DMC55 Electronic Controller

The CD-VS series is equipped with the DMC55 electronic controller, which has an intuitive user interface with its 4.3” capacitive touch screen display and multiple functions. The controller constantly monitors the operating pressure and temperature values and adjusts the compressor and fan speeds. This ensures an extremely stable dew-point under all operating conditions.

THE NEW MAIN FUNCTIONS INTRODUCED ARE:

  • Weekly on-off programming
  • Display of instantaneous electrical power input
  • Display of spare-parts list
  • Dryer management via Modbus RS485 RTU communication (Industry 4.0 ready)

Electronic hot gas by-pass Valve – EHGBV

The electronic hot gas bypass valve EHGBV directly controlled by the DMC55, introduced a No-cycling mode. This function allows maximum performance even in conditions of low thermal loads: the compressor, in this condition, never shuts down, remaining at minimum speed and delegating the cooling capacity control to the EHGBV, which guarantees continuous and stable regulation.

Five operating modes

The CD-VS range is equipped with intelligent/automatic management of five operating modes, which can be set directly from the controller display:

  • Performance
  • Standard
  • ECO
  • ECO Plus
  • AODOM
